think about this, THC is absorbed instantly in the lungs right? what about all the smoke in your lungs that doesn't actually touch your lungs before you blow it out prematurely? smoke needs quite a few seconds to actually circulate through your lungs, so holding in hits is necessary.

I usually hold mine in for at least 5 good seconds or more.
